SPX1582 3A超低压差稳压器

The SPX1582 is a 3A Low Dropout Regulator with extremely low dropout voltage. The adjustable version requires only two external resistors to set the output voltage. The fixed version has a preset output of 3.3V, 2.8V or 2.5V and does not require any external resistors. The SPX1582 features a low dropout of 400mV(Typ.) and offers fast transient response. This device is suitable for Pentium applications requiring 2.8V, 2.5V from 3.3V ATX power supplies, where low current input voltage 1V greater than the output voltage is needed. With an external sense pin the load regulation is less than 1mV. This device is an excellent choice for the use in powering low voltage microprocessors that require a lower dropout, fast transient response to regulate from 3.3V and 5V supplies. The SPX1582 is also an excellent choice as a post regulator for switching supply applications.
